Multispindle automatic lathe - has number of spindles on spindle carrier which is supported indexable and rotatably by head stock

摘要

The multispindle automatic lathe rotatably supports a number of spindles on a spindle carrier (52) which is supported indexably and rotatably by a head stock (51) and which is equipped with a single motor (20) for driving and rotating the spindles (55) in order to prevent mutual and spatial interference between the motor (20) and an elongated work-piece (W) when the elongated workpiece is machined. The automatic lathe is characterised in that the axis of rotation of the spindle carrier (52) and the rotary output shaft (21) of the motor (20) are disposed on the same axis, with drives (57) for transmitting the rotation output of the motor (20) to the spindles are provided and a through-hole (37) is formed in the stator (29) portion of the motor (20) so that it exists on the same axis as that of the centre hole of the number of spindles (55). @(17pp Dwg.No.3/5)@.
